Exploring Boundaries...

I'm in my early twenties, and I've been in an open relationship for about a year now. It's not that it's hard to be non-monogamous; it just feels like there's always this underlying current of 'what if?' nagging at the back of my mind. Recently, I found myself drawn to someone outside our arrangement... or rather, they found me first. We started talking more and realized we had a lot in common. It was exciting, but also left me questioning everything - is it because I'm seeking something new? Or are these feelings just about the thrill of the forbidden? Last night, we took things further than just chatting, and now here I am... trying to understand why this feels both exhilarating and frightening at once. I want honesty in my relationships but also crave the spontaneity that comes with stepping outside established boundaries...
